ENOTTY··on A threat analysis of sideloading [pdf]
I think Apple makes great products and skimming through the paper, I find this analysis to be on-target. But this is coming from an obviously biased source.

As with most things in security, it's a trade-off between competing goals and principles.

ENOTTY··on Facebook Whistleblower Leaks Thousands of Pages of Incriminating Internal Docs
This might fall under Matt Levine's theory that "everything is securities fraud"
ENOTTY··on Facebook Is a Hostile Foreign Power
One has to wonder how a company like Facebook would be treated under a regime like China's.
ENOTTY··on MacKenzie Scott’s Money Bombs Are Single Handedly Reshaping America
I don’t think she particularly cares about measuring the effectiveness of her altruism.

> “What do we think they might do with more cash on hand than they expected?” Scott asked in her June blog post. “Hire a few extra team members they know they can pay for the next five years. Buy chairs for them. Stop having to work every weekend. Get some sleep.”

My wild ass guess is that she’s hoping her firehose of money will do more good in a shorter amount of time versus spending a lot of time fine tuning the giving.

I think a lot of billionaire philanthropists see their giving as almost like a kind of investment, and some of them want to see a return on that investment that is above the average return from the average non-billionaire giver. That in turn causes the recipient to spend at least some time thinking about how to make that billionaire feel like they got a good return.

It sounds like McKenzie-Scott’s idea of giving is more hands off, identifying teams that had a history of doing good work, and giving them both resources and mental space to execute.

Something for effective altruists to consider.

ENOTTY··on Apple iPhone charger teardown: quality in a tiny expensive package (2012)
Have you torn down any more recent chargers? Curious if quality standards for Apple or other consumer electronics companies have held steady, improved, or gotten worse in the 9 intervening years.
ENOTTY··on A case against security nihilism
The 'economic' argument simply doesn't work. Does the author think that every "tin-pot authoritarian" owns a poor country scrabbling in the unproductive desert for scraps? Of course not!

Literally one of the best customers of NSO tools is Saudi Arabia (SA), where money literally bursts out of the ground in the form of crude oil. The market cap of Saudi Aramco is 3x that of Apple's. Good luck making it "uneconomical" for SA to exploit iPhones.

I'll even posit that there is literally no reasonable amount where the government of SA cannot afford an exploitation tool. The governments that purchase these tools aren't doing it for shits and giggles. They're doing it because they believe that their targets represent threats to their continued existence.

Think of it this way, if it costs you a trillion dollars to preserve your access to six trillion dollars worth of wealth, would you spend that? I would, in a heartbeat.

There's definitely room in the e2e messaging space that is more corporate oriented. Think centralized administration, key escrow, etc.

ENOTTY··on North Carolina tells retired engineer he can't talk about engineering
This is a sympathetic framing on an attempt to chip away at licensing requirements. Not saying whether that’s good or bad, just want to point it out
ENOTTY··on Two Hidden Instructions Discovered in Intel CPUs Enable Microcode Modification
From the US Treasury press release announcing the sanctions:

> Positive Technologies is a Russian IT security firm that supports Russian Government clients, including the FSB. Positive Technologies provides computer network security solutions to Russian businesses, foreign governments, and international companies and hosts large-scale conventions that are used as recruiting events for the FSB and GRU.

ENOTTY··on In Response to Oversight Board, Trump Suspended for Two Years
I also believe that aggressive antitrust may address the concerns I raise.

But at the same time, I am sympathetic to arguments that aggregated platforms have efficiencies that are passed down to the everyday consumer, or network effects that make the platforms more competitive against similar platforms elsewhere in the world (e.g., data for training ML models).

ENOTTY··on In Response to Oversight Board, Trump Suspended for Two Years
My argument is that because Facebook is huge and used by many Americans, there should be limits on what Facebook can do to its users.

Now I personally don't know what all of those limits should be. But I think there needs to be more open discussion from all corners of American society about that. I also think that the platforms should approach this problem with open arms.

As an example of one situation that needs to be limited is that a platform like Google is allowed to ban someone entirely from their services, with 1) no appeal to an independent party and 2) no ability to (quickly) recover data stored with that platform. Every so often, someone posts to HN saying that they lost all access to decades of email and photos because Google's algorithms banned them, and they have no idea how to talk to a human to explain or correct the situation. I think that kind of action from Google needs to be regulated out of existence.

ENOTTY··on In Response to Oversight Board, Trump Suspended for Two Years
I'm pretty onboard, but uneasy, with the framing that private entities should have broad discretion to decide how to govern the use of their spaces.

But Facebook (and Google, Apple, and many other "platforms") are such an indispensable part of our lives that we should have difficult conversations about what individual rights look like in these quasi-public private spaces. (It's worth noting that the explicit business model of many of these companies is to create gigantic platforms/walled gardens.)

I personally do not believe that many of the norms and common law relating to physical public/private spaces should be transferred to the modern age of digital oligopoly.

ENOTTY··on Censorship, Surveillance and Profits: A Hard Bargain for Apple in China
Google left China because it discovered it was the victim of a cyberattack from the Chinese government, not really out of any kind of hate of authoritarianism. https://en.wikipedia.org/wiki/Operation_Aurora

And they returned to the Chinese market several years later.

Part of it is media bias. Lots of media centered around NYC and Washington DC.

What would you have them do? Leave the Chinese market? Try to operate illegally? In both the Chinese and US markets, seems like Apple did everything they legally could.
ENOTTY··on Tech giants join call for funding U.S. chip production
I don't know how you can justifiably call Africa a has-been. Africa is by far the youngest continent in the world, with 60% of the population below 25. The median age is 19. The fertility rate is incredibly high. Most likely, Africa is the continent of the future.

ENOTTY··on “They introduce kernel bugs on purpose”
I just wanted to highlight that S&P/Oakland is one of the top 3 or 4 security conferences in the security community in academia. This is a prestigious venue lending its credibility to this paper.
ENOTTY··on “They introduce kernel bugs on purpose”
Later down thread from Greg K-H:

> Because of this, I will now have to ban all future contributions from your University.

Understandable from gkh, but I feel sorry for any unrelated research happening at University of Minnesota.

EDIT: Searching through the source code[1] reveals contributions to the kernel from umn.edu emails in the form of an AppleTalk driver and support for the kernel on PowerPC architectures.

In the commit traffic[2], I think all patches have come from people currently being advised by Kangjie Liu[3] or Liu himself dating back to Dec 2018. In 2018, Wenwen Wang was submitting patches; during this time he was a postdoc at UMN and co-authored a paper with Liu[4].

Prior to 2018, commits involving UMN folks appeared in 2014, 2013, and 2008. None of these people appear to be associated with Liu in any significant way.

ENOTTY··on Proposed acquisition of ARM Limited by NVIDIA: public interest intervention
Can you describe what you mean by disaggregated?

From what I can tell, there seems to be increasing consolidation in the industry:

* AMD -- Xilinx -- ATI

* Nvidia -- ARM -- Mellanox

* Intel -- Altera -- Habana/Nervana -- Mobileye

ENOTTY··on Huawei was able to eavesdrop on Dutch mobile network KPN: Report
The article seems poorly translated (into English), so I’m going to avoid reading too much into it.

But one thing I want to highlight is the fact that this story appears to be based off a report written by a consulting firm, Capgemini. For that reason alone I would bet that this report identifies hypothetical risks, not actual instances of unauthorized access.

ENOTTY··on U.S. adds Chinese supercomputing entities to economic blacklist
Ellen Nakashima of the Washington Post wrote two in-depth articles on this topic over the past couple days:

* https://www.washingtonpost.com/national-security/china-hyper...

* https://www.washingtonpost.com/national-security/biden-admin...

The TL;DR is that one of the sanctioned companies, Phytium, designs chips used in a Chinese supercomputer that the PLA's researchers use to simulate hypersonic weapons. The chips are designed using tools from Cadence and Synopsys (both American companies) and fabricated at TSMC.

ENOTTY··on SolarWinds speaks out, and software dev can never be the same again
> For example, SolarWinds now conducts a two-way build. The code is pulled from source code control, built, hashed, then decompiled and compared back to the original, to ensure what ships is what was coded and nothing more or less.

This seems like a high-labor and error-prone way to detect a possible integrity compromise of your build infrastructure. Maybe they've done this, but what software shops need to do is better control the integrity of their build infrastructure and the confidentiality of their code signing keys.

Ideally, build infrastructure would be immutable (resistant to unauthorized change), burnable (defeats persistence), and auditable (changes need to authorized and logged). The build infrastructure itself would produce auditable artifacts from the build, including hashes of input files, compilers, etc.
